This specification is intended to be taken asa whole and interpreted in accordance with the principles of the presentdisclosure and as understood by one of ordinary skill in the art.

FIGS. 1A to 14E illustrate one example embodiment of a lumber handlingand cutting apparatus of the present disclosure generally indicated bynumeral 50 (and sometimes referred to herein as the “apparatus” forbrevity). FIGS. 1A to 14E show selected components of the apparatus 50during the handling and cutting of different example lumber boards thatmay be used to manufacture trusses, joists, other such lumber supportedstructures, or otherwise. Various other components of the apparatus 50not discussed herein will be readily understood by those skilled in theart.

As best shown in FIGS. 1A to 14E, the illustrated example apparatus 50includes various stations including: (1) an incoming material conveyorassembly 100; (2) a printer assembly 200 adjacently positioned and/orconnected to the incoming material conveyor assembly 100; (3) a materialinfeed assembly 300 adjacently positioned and/or connected to theincoming material conveyor assembly 100; (4) a cutting assembly 400adjacently positioned and/or connected to the infeed assembly 300; (5) amaterial outfeed assembly 500 adjacently positioned and/or connected tothe cutting assembly 400; and (6) an outgoing material conveyor assembly600 adjacently positioned and/or connected to the material outfeedassembly 500.

The incoming material conveyor assembly 100 of the apparatus 50 isconfigured to receive material such as lumber for processing by theapparatus 50. More specifically, as best shown in FIGS. 1A to 1D, 2, and3A to 4E, the incoming material conveyor assembly 100 includes: (1) asupport frame 110; (2) a plurality of feed members 120 supported by andsuitably connected to the support frame 110; (3) a conveyor member 130suitably connected to each of the feed members 120; and (4) a conveyordrive assembly 140 supported by the support frame 110 and/or theplurality of feed members 120. The conveyor drive assembly 140 issuitably connected to and engaged with the conveyor member 130 connectedto each of the feed members 120. The conveyor drive assembly 140 and theconveyor member 130 are configured to support and move lumber boards (ofdifferent dimensions) on each of the feed members 120 as the lumberboards move toward and to the printer assembly 200 and toward and to thematerial infeed assembly 300. The incoming material conveyor assembly100 thus provides a suitable support structure for receiving andconveying material such as lumber boards (of different dimensions) to beprocessed by the apparatus 50. It should be appreciated that theincoming material conveyor assembly 100 may be otherwise suitablyconfigured in accordance with the present disclosure.

The printer assembly 200 of the apparatus 50 enables the apparatus 50 toprint on or otherwise mark each of the lumber boards before processingthe lumber boards by the cutting assembly 400. More specifically, asbest shown in FIGS. 1A to 1D, 2, and 3A to 4E, the printer assembly 200includes: (1) a printer support base 210; (2) a 220 printer supportframe supported by and suitably connected to the printer support base210; (3) a printer support arm 230 supported by and suitably connectedto the printer support frame 220; (4) a print head mounting bracket 240connected to the printer support arm 230; (5) a print head 250 supportedby and suitably connected to the print head mounting bracket 240; and(6) a multi-size board alignment assembly 260 positioned at an end of atleast one of the feed members 120 of the incoming material conveyorassembly 100. The print head 250 is positioned in a downward facingmanner to print on each of the lumber boards (of different dimensions)as each of the lumber boards passes underneath the print head 250 at atransition point as further described below.

The printer assembly 200 enables printing on a designated surface (i.e.,a top, bottom, or side surface) of each of the lumber boards (ofdifferent dimensions) as each of the lumber boards are fed from theincoming material conveyor assembly 100 to the material infeed assembly300. It should be understood that lumber may sometimes be used herein torefer to one or more lumber boards (which also includes any suitablepieces of lumber that is or can be processed by the apparatus 50). Inthis illustrated example embodiment, the printer assembly 200 ispositioned at a transition point between the incoming material conveyorassembly 100 and the infeed conveyor 310 of the material infeed assembly300.

The printer support frame 220 positions (or enables positioning) of theprinter support arm 230 over the top of or above the incoming lumberboard at the transition point. Accordingly, the print head mountingbracket 240 is attached to the printer support arm 230 such that theprint head 250 is positioned above each incoming lumber board at thetransition point. In the illustrated example embodiment, the print head250 faces downward and prints on the designated surface of each lumberboard as that lumber board passes underneath the print head 250. Theprinter assembly 200 further includes at least one multi-size boardalignment assembly 260 connected to the feed members 120 of the incomingmaterial conveyor assembly 100. In the illustrated example, themulti-size board alignment assembly 260 is located at the transitionpoint between the feed members 120 and the infeed conveyor 310. Themulti-size board alignment assembly 260 enables the apparatus 50 tosquare or otherwise align each incoming lumber board with respect to theprint head 250 for a suitable period of time as that lumber board passesunderneath the print head 250.

In the illustrated example, the multi-size board alignment assembly 260enables the printer assembly 200 to print on each incoming lumber boardhaving one of a variety of different orientations, shapes, dimensionsand/or sizes without adjusting and/or reconfiguring the printer assembly200 and/or the apparatus 50.

For example, as best seen in FIGS. 3A to 3E, the printer assembly 200 isconfigured to print on a lumber board (not labeled) having a first setof dimensions and/or orientation (e.g., 4×2 or 3×2) as that lumber boardpasses underneath the print head 250. The incoming material conveyorassembly 100 delivers that lumber board up to a manual stop (not shown)that squares the lumber board prior to passing underneath the print head250 for a suitable period of time. Once that lumber board is squared orotherwise aligned, the material conveyor assembly 100 may back thatlumber board up a small amount such that the manual stop can be lowered.The incoming material conveyor assembly 100 feeds that lumber boardforward at a set speed. As the lumber board feeds forward, a printsensor 262 detects the presence of that lumber board and activates theprint head 250. The print head 250 prints on the designated surface ofthat lumber board as that lumber board is fed from the incoming materialconveyor assembly 100 to the material infeed assembly 200. While movingforward underneath the print head 250, that lumber board contacts themulti-size board alignment assembly 260 that re-squares or otherwisemaintains alignment of that lumber board as that lumber board passesunderneath the print head 250. That is, the multi-size board alignmentassembly 260 helps to maintain the print position (e.g., flat orhorizontal) of that lumber board with respect to the print head 250 asthat lumber board passes underneath the print head 250. At the pointthat the lumber board is over half way underneath the print head 250,the lumber board center of gravity will pass over the center of themulti-size board alignment assembly 260 causing that lumber board tofeed downwardly into the infeed conveyor 310 of the material infeedassembly 300. The next lumber board can then subsequently transitionunder the print head 250 for printing. This printing process willcontinue until the last lumber board for the particular job iscompleted.

As best seen in FIGS. 4A to 4E, the printer assembly 200 prints on alumber board (not labeled) having a second different set of dimensionsand/or orientation (e.g., 2×12) as that lumber board passes underneaththe print head 250. The incoming material conveyor assembly 100 deliversthat lumber board up to a manual stop (not shown) that squares thelumber board prior to passing underneath the print head 250 for asuitable period of time. Once that lumber board is squared or otherwisealigned, the material conveyor assembly 100 may back that lumber boardup a small amount such that the manual stop can be lowered. The incomingmaterial conveyor assembly 100 feeds that lumber board forward at a setspeed. As that lumber board feeds forward, a print sensor 262 detectsthe presence of that lumber board and activates the print head 250. Theprint head 250 prints on the designated surface of that lumber board asthat lumber board is fed from the incoming material conveyor assembly100 to the material infeed assembly 200. While moving forward underneaththe print head 250, that lumber board contacts the multi-size boardalignment assembly 260 that re-squares or otherwise maintains alignmentof that lumber board as that lumber board passes underneath the printhead 250. That is, the multi-size board alignment assembly 260 helps tomaintain the print position (e.g., flat or horizontal) of that lumberboard with respect to the print head 250 as that lumber board passesunderneath the print head 250. At the point that the lumber board isover half way underneath the print head 250, the lumber board center ofgravity will pass over the center of the multi-size board alignmentassembly 260 causing the lumber board to feed downwardly into the infeedconveyor 310 of the material infeed assembly 300. The next lumber boardcan then transition under the print head 250 for printing. The processof printing will continue until the last lumber board for the particularjob is completed.

In various embodiments of the present disclosure, the printer supportarm 230 that extends over the lumber board and the print head mountingbracket 240 is slidable along the printer support arm 230 such that theprint head 250 prints at a desired location along the designated surfaceof each lumber board. Furthermore, the printer support arm 230 may beconfigured to rotate back from the position over the lumber board toenable cleaning or other maintenance of the print head 250.

In various embodiments of the present disclosure, the multi-size boardalignment assembly 260 includes one or more idler rollers that is/areeach positioned at an end of one or more respective feed members 120 ofthe incoming material conveyor assembly 100. In certain embodiments ofthe present disclosure, the multi-size board alignment assembly 260includes one or more idler rollers that is/are otherwise suitablyconnected to or otherwise attached to one or more feed members 120 ofthe incoming material conveyor assembly 100. The multi-size boardalignment assembly 260 enables the lumber board to smoothly transitionfrom the incoming material conveyor assembly 100 to the infeed assembly300. The multi-size board alignment assembly 260 further enables theprinter assembly 200 to square (or re-square) each lumber board as thatlumber board passes underneath the print head 250 for printing. Thus,the multi-size board alignment assembly 260 enables the printer assembly200 to print on the designated surface of lumber having a variety ofdifferent dimensions and/or orientations (such as but not limited to3×2, 4×2, and/or 2×12 lumber boards) without adjusting or reconfiguringthe setup of the apparatus 50.

It should thus be appreciated that in various embodiments of the presentdisclosure, the multi-board alignment assembly 260 is positioned at anend of one or more feed members 120 of the incoming material conveyorassembly 100.

In various embodiments of the present disclosure, the multi-size boardalignment assembly 260 is suitably connected or otherwise attached toone or more feed members 120 of the incoming material conveyor assembly100.

In various alternative embodiments of the present disclosure, themulti-size board alignment assembly 260 may be alternatively attached tothe infeed conveyor 310 of the material infeed assembly 300.

In various alternative embodiments of the present disclosure, themulti-size board alignment assembly 260 can be configured to include oneor more independently driven rollers that feed(s), square(s) andalign(s) each lumber board as that lumber board is printed on by theprinter assembly 200.

In various alternative embodiments of the present disclosure, theprinter assembly 200 may be configured such that the print head 250 ispositioned below the lumber board. As such, the print head 250 prints onor otherwise marks each lumber board as that lumber board passes overthe print head 250.

Referring now to FIGS. 5A to 12D, the material infeed assembly 300 ofthe apparatus 50 is configured to receive each lumber board after thatlumber board is printed on by the printer assembly 200. Morespecifically, the material infeed assembly 300 is configured to align,orient (or re-orient), and support each lumber board before that lumberboard is fed into the cutting assembly 400. In the illustrated example,the material infeed assembly 300 includes: (1) an infeed conveyor 310adjacently positioned and/or connected to at least one of the feedmembers 120 of the incoming material conveyor assembly 100; (2) a stopmember 320 connected to the infeed conveyor 310; (3) a drag chain or adogged chain conveyor 330 adjacent to the end of the infeed conveyor 310and the stop member 320; (4) an actuator mounting bracket 340 suitablyconnected to the infeed conveyor 310; (5) an actuator or actuator member350 supported by and suitably connected to the actuator mounting bracket340; (6) a lifting member 360 suitably connected to the actuator member350; (7) a guide member 370 suitably connected to the infeed conveyor310; (8) an inner support member 380 suitably connected to the stopmember 320 and the infeed conveyor 310; and (9) an outer support member390 suitably connected to the infeed conveyor 310.

As best illustrated in FIGS. 5A to 5E, 6A to 6E, and 7A to 7D, theinfeed assembly 300 includes the lifting member 360 configured to engagewith and change (if needed) the orientation (or re-orientation) of eachlumber board before that lumber board is fed into the cutting assembly400. The lifting member 360 includes: (1) a lifting member arm 362; (2)a lifting member hand portion 364 defined at an end of the liftingmember arm 362; and (3) a lifting member finger 366 connected to thelifting member hand portion 364. The lifting member 360 also includes(4) a lifting member notch 368 defined in or by the lifting member handportion 364 and/or the lifting member finger 366.

FIGS. 5A to 5E illustrate one example progression through the materialinfeed assembly 300 of a first example lumber board (not labeled) havinga first size and orientation (such as 3×2, 2×3, or other suitable sizeand orientation). As the lumber board is fed from the incoming materialconveyor assembly 100, the apparatus 50 causes the lifting member 360 tobe in an extended position. In this illustrated example embodiment, thelifting member 360 is partially supported by a guide member 370. Theguide member 370 may be a roller or other suitable member that contactsor is contacted by the lifting member 360 as the actuating member 350extends and retracts the lifting member 360 (forwardly and rearwardly,respectively). With the lifting member 360 in the extended position, theinfeed assembly 300 receives a lumber board on the infeed conveyor 310.In this illustrated example embodiment, the infeed conveyor 310 issloped such that the lumber board slides down the infeed conveyor 310and contacts the lifting member 360 in the horizontal orientation, asshown in FIG. 5A. The actuating member 350 then retracts the liftingmember 360 which in turn causes the lumber board to engage with the stopmember 320, as shown in FIG. 5B. The actuating member 350 then extendsthe lifting member 360 such that the lifting member finger 366 engages asurface and/or an edge (e.g., bottom surface, and/or front edge) of thelumber board, as shown in FIG. 5C. The engagement between the liftingmember finger 366 and the movement of the lifting member 360 and thelumber board causes the lumber board to rotate and/or slide into thelifting member notch 368 of the lifting member hand portion 364, asshown in FIGS. 5C and 5D. The actuating member 350 continues to extendthe lifting member 360 such that the plurality of dogs of the doggedchain conveyor 330 grab the 3×2 lumber board in the desired orientation,as shown in FIG. 5E. Accordingly, the dogged chain conveyor 330 receivesthe 3×2 lumber board and feeds that lumber board into the cuttingassembly 400 of the apparatus 50. This enables the next lumber board todrop down the infeed conveyor 310 and the progression repeats itselfuntil all of the lumber boards are processed.

FIGS. 6A to 6E illustrate another example progression through thematerial infeed assembly 300 of a second example lumber board (notlabeled) having a different second size and orientation (such as 4×2,2×4, or other suitable size and orientation). As the lumber board is fedfrom the incoming material conveyor assembly 100, the lifting member 360is in an extended position, as shown in FIG. 6A. In this illustratedexample, the lifting member 360 is partially supported by the guidemember 370. The guide member 370 may be a roller or other suitablemember that contacts or is contacted by the lifting member 360 as theactuating member 350 extends and retracts the lifting member 360. Withthe lifting member 360 in the extended position, the infeed assembly 300receives a lumber board on the infeed conveyor 310. The infeed conveyor310 may be sloped such that the lumber board slides down the infeedconveyor 310 and contacts the lifting member 360 in the horizontalorientation. The actuating member 350 then retracts the lifting member360 and the lumber board engages with the stop member 320, as shown inFIG. 6B. The actuating member 350 then extends the lifting member 360such that the lifting member finger 366 engages a surface and/or an edge(e.g., bottom surface, and/or front edge) of the lumber board, as shownin FIG. 6C. The engagement between the lifting member finger 366 and thelumber board and the movement of the lifting member 360 causes thelumber board to rotate and/or slide into the lifting member notch 368 ofthe lifting member hand portion 364, as shown in FIGS. 6C and 6D. Theactuating member 350 continues to extend the lifting member 360 suchthat the plurality of dogs of the dogged chain conveyor 330 grab thelumber board in the desired orientation, as shown in FIG. 6E.Accordingly, the dogged chain conveyor 330 receives the lumber board andfeeds the lumber board into the cutting assembly 400 of the apparatus50. The next lumber board can then drop down the infeed conveyor 310 andthe progression repeats itself until all of the lumber boards areprocessed.

In various example embodiments, the apparatus 50 may be initially set upfor a single lumber board size and/or orientation (e.g., 3×2, 4×2, orother such size and/or orientation). The apparatus 50 is configured tocontrol the actuating member 350 such that the lifting member 360 limitsthe engagement of the plurality of dogs on the dogged chain conveyor 330such that the lumber boards (e.g., 3×2 or 4×2 lumber boards) can be fedinto the cutting assembly 400. The actuating member 350 and the liftingmember 360 are configured such that the material infeed assembly 300enables the apparatus to feed lumber into the cutting assembly 400 thatis 90 degrees to the normal or standard orientation. This enables theapparatus 50 to feed lumber having the same orientation into the cuttingassembly 400 for different size lumber boards such as, for example, both3×2 lumber boards and 4×2 lumber boards.

FIGS. 7A to 7E illustrate another example progression through thematerial infeed assembly 300 of a third example lumber board (notlabeled) having a different third size and orientation such as 2×12. Inthe illustrated example embodiment, lumber board having the 2×12dimensions and orientation does not require the lifting member 360 tore-orient this lumber board as the lumber board is fed into the doggedchain conveyor 330. Accordingly, as the lumber board is fed from theincoming material conveyor assembly 100, the actuating member 350remains in a retracted or otherwise non-actuated position, as shown inFIG. 7A. The infeed assembly 300 receives a lumber board on the infeedconveyor 310. The infeed conveyor 310 is sloped such that the lumberboard slides down the infeed conveyor 310. The actuating member 350remains in the retracted position and the lumber board engages with thestop member 320, as shown in FIG. 7B. The plurality of dogs of thedogged chain conveyor 330 grab the 2×12 lumber board in the desiredorientation, as shown in FIG. 7C. Accordingly, the dogged chain conveyor330 receives the lumber board and feeds the lumber board into thecutting assembly 400 of the apparatus 50. The next lumber board can thendrop down the infeed conveyor 310 and the progression repeats itselfuntil all of the lumber boards are processed.

It should be appreciated that the apparatus 50 can include one or moresensors (not shown) or other suitable mechanisms (not shown) at one ormore of the stations of the apparatus to determine the dimensions ofeach lumber board processed by the apparatus 50.

It should also be appreciated that the apparatus 50 can include one ormore controllers (not shown) or other suitable mechanisms (not shown) toreceive inputs from such sensors or other suitable mechanisms to controleach of the different stations and operations of the apparatus 50.

In various embodiments, the apparatus 50 may include the infeed conveyor310 as or in the form of two or more infeed conveyors such as infeedconveyors 310 a and 310 b; and may include the dogged chain conveyor 330as or in the form of two or more dogged chain conveyors such asconveyors 330 a and 330 b spaced apart from one another. One suchexample embodiment is shown by infeed conveyors 310 a and 310 b anddogged chain conveyors 330 a and 330 b in FIGS. 8 to 12D. It should alsobe appreciated that in certain such example embodiments, each infeedconveyor 310 a and 320 b may include a lifting member 360 and anactuating member 350 for orienting each lumber board as that lumberboard is fed from the infeed conveyors 310 to the dogged chain conveyors330 a and 330 b.

FIGS. 8 to 11 and 12A to 12D illustrate one example embodiment of theinfeed assembly 300 that includes the example inner and outer supportmembers 380 and 390 suitably connected to the infeed conveyor 310. Inthis illustrated example embodiment, the apparatus 50 has two infeedconveyors 310 a and 310 b, spaced apart from one another. Furthermore,the apparatus 50 includes two dogged chain conveyors 330 a and 330 bconfigured to receive lumber boards from the infeed conveyors 310 a and310 b. The inner support member 380 is connected to and supports thestop member 320 and a lumber alignment member 322 of the infeed conveyor310 a (e.g., the infeed conveyor on the right side of apparatus 50). Asa result, the inner support member 380 provides support such that thelumber board does not fall off the inside portion of the infeed conveyor310 a. Additionally, the outside support member 390 is suitablyconnected to and supports the infeed conveyor 310 b (e.g., the infeedconveyor on the left side of the apparatus 50). The outer support member390 supports the lumber board such that the apparatus 50 may processincoming lumber boards that are longer (e.g., one foot or more longer)than the desired final cut length of such lumber boards. As such, theinner and outer support members 380 and 390 are configured to supporteach lumber board as the lumber board traverses along the infeedconveyor 310 a and 310 b and up along the sides of the dogged chainconveyor 330 a and 330 b until the dogs establish a grip on the lumberboard.

FIGS. 12A to 12D illustrate one example progression of a lumber board(not labeled) through the material infeed assembly 300 while the lumberboard is supported by the inner and outer support members 380 and 390.In the illustrated example, the apparatus 50 feeds the lumber boardforward at a set speed. The lumber board traverses down the infeedconveyors 310 a and 310 b towards the dogged chain conveyor 330 a and330 b. If the lumber board traversing down the infeed conveyors 310 aand 310 b is unstable, the respective first downwardly inclined portions(not separately labeled) of the inner and outer support members 380 and390 will support the lumber board such that the lumber board does nottip or otherwise fall off of the infeed conveyors 310 a and 310 b. Asthe lumber board traverses down the infeed conveyors 310 a and 310 b,the lumber board is grabbed by one or more dogs of the dogged chainconveyors 330 a and 330 b. The lumber board then traverses up the doggedchain conveyors 330 a and 330 b following the contour of the doggedchain conveyors 330 a and 330 b. In the illustrated example, the one ormore dogs temporarily release the lumber board at a transition pointbetween the material infeed assembly 300 and the cutting assembly 400.The lumber alignment member 322 (e.g., alignment wheel) aligns thelumber board at this transition point prior to processing of the lumberboard by the cutting assembly 400. The respective second upwardly curvedportions (not separately labeled) of the inner and outer support members380 and 390 are configured to maintain support of the lumber board whileallowing the lumber board to slide during lumber alignment by the lumberalignment member 322. Following the lumber alignment, one or more dogsof the dogged chain conveyors 330 a and 330 b grip or re-grip the lumberboard in the aligned position. The lumber board is now properly alignedand ready for processing by the cutting assembly 400. As a result, thelumber board no longer needs support by the inner and outer supportmembers 380 and 390. The dogged chain conveyors 330 a and 330 b thenfeed the lumber board into the cutting assembly 400.

In various embodiments, the inner and outer support members 380 and 390are shaped to follow the top contour of the side plates of dogged chainconveyors 330 a and 330 b. Such contours of the inner and outer supportmembers 380 and 390 enable the material infeed assembly 300 to maintaincontact with and support of the lumber board as the lumber boardtraverses from the infeed conveyors 310 a and 310 b and up the doggedchain conveyors 330 a and 330 b.

In various example embodiments, the inner and outer support members 380and 390 are connected to the infeed conveyors 310 a and 310 b with asuitable pivot member (not shown or labeled) to adjust the position ofthe inner and outer support members 380 and 390 with respect to theinfeed conveyors 310 a and 310 b and the dogged chain conveyors 330 aand 330 b.

In various embodiments, the inner and outer support members 380 and 390further include one or more mounting positions (not labeled) for sensorsand other components of the apparatus 50. The one or more mountingpositions may be configured to protect the sensors from the incominglumber and moving components of the apparatus 50.

It should be appreciated from the above that in various embodiments theapparatus 50 may be set up for processing lumber boards having differentdimensions and/or orientations. For example, if the apparatus 50 is setup to process lumber with different dimensions and orientation such as4×2, and/or 3×2, the outer support member 390 may further include asupport structure that is positioned on top of the outer support member390. The support structure may be suitably connected to the outersupport structure 390 with a plurality of pins or other such suitablefasteners.

It should be appreciated from the above that in various embodiments, theinner and outer support members 380 and 390 are configured to providesupport for each lumber board at a transition point between the infeedconveyors 310 a and 310 b and the dogged chain conveyors 330 a and 330b. The inner and outer support members 380 and 390 maintain support ofthe lumber board as the lumber board traverses along the dogged chainconveyors 330 a and 330 b.

It should be appreciated from the above that in various embodiments, theinner and outer support members 380 and 390 are configured to supporteach lumber board at an alignment point along the dogged chain conveyors330 a and 330 b. For example, the alignment point is at the locationwhere the dogged chain conveyor 330 a passes the lumber alignment wheel322. It should be appreciated from the above that at this alignmentpoint, the dogs of the dogged chain conveyors 330 a and 330 b may loosenthe grip on the lumber board to enable the lumber alignment member 322to align the lumber board for processing by the cutting assembly 400.The inner and outer support members 380 and 390 support the lumber boardduring this alignment by the lumber alignment member 322.

It should be further be appreciated from the above that after eachlumber board is received and properly oriented, the material infeedassembly 300 feeds the lumber board to the cutting assembly 400. Thecutting assembly 400 is configured to cut or otherwise process eachlumber board that is fed into the apparatus 50. More specifically, asbest shown in FIGS. 1A to 4E, the example cutting assembly 400 includes:(1) a cutting support frame 410; (2) a cutting conveyor 420 supported bythe cutting support frame 410; (3) a saw assembly 430 supported by andsuitably connected to the cutting support frame 410; and (4) a sawenclosure member 440 supported by the cutting support frame 410 suchthat the saw assembly 430 is enclosed. The cutting conveyor 420 issuitably connected to the dogged chain conveyor 330 of the materialinfeed assembly 300. As such, the cutting assembly 400 receives a lumberboard from the material infeed apparatus 300 and processes (e.g., cutsor saws) that lumber board according to the desired final dimensions forthat lumber board. It should be appreciated that in this illustratedexample embodiment, the cutting conveyor 420 and the saw assembly 430are obscured by the saw enclosure member 440 and therefore labeled usingdashed lines.

In various embodiments, the dogged chain conveyor 330, the cuttingconveyor 420 and the saw assembly 430 are each supported by and suitablyattached to the cutting support frame 410 of the cutting assembly 400.

The material outfeed assembly 500 is configured to orient and/orreorient each of the lumber boards such that each lumber board ends upon a specific side following processing by the cutting assembly 400. Asillustrated in FIGS. 1A, 1B, 1C, and 13A to 14E, the material outfeedassembly 500 includes: (1) an outfeed conveyor 510 connected to thecutting conveyor 420; (2) an outfeed orientation member 520 suitablyattached on either side of the outfeed conveyor 510; (3) an outfeedorienter 530 defined in the outfeed orientation member 520; and (4) anoutfeed slide portion 540 defined in the orientation member 520.

FIGS. 13A to 13E and 14A to 14E illustrate one example material outfeedassembly 500 of the present disclosure that is configured to receive andreorient a variety of different lumber sizes as the lumber is outputfrom the cutting assembly 400. In the illustrated example, the materialoutfeed assembly 500 is configured to lift at least one edge of eachlumber board as that lumber board comes out of the cutting assembly 400.As a result, the lumber board rotates such that the lumber board fallsin a controlled manner onto a specific side as the lumber board is fedout of the apparatus 50.

As best seen in FIGS. 13A to 13E, the progression of a lumber board (notlabeled) having a first size and orientation (e.g., 4×2) along thematerial outfeed assembly 500 is shown. The lumber board is pushed orotherwise fed along the outfeed conveyor 510 by an outfeed conveyor dog512. The lumber board traverses along the outfeed orienter 530 such thatthe lumber board rotates about a top portion (not labeled) of an outfeedconveyor dog 512 before the lumber board is released to the outgoingmaterial conveyor assembly 600. More specifically, the outfeed orienter530 is shaped to define or otherwise include an incline portion 532(facing the cutting assembly 400) that enables the outfeed orienter 530to tip or rotate the lumber board. Accordingly, as the lumber boardtraverses along the outfeed orienter 530, the incline portion 532 isconfigured to cause rotation of the lumber board about the top of theoutfeed conveyor dog 512 at an angle 514 that is past the center ofgravity 515 for the lumber board. Thus, the lumber board tips over in acontrolled and desired manner to reorient the lumber board as the lumberboard is fed out of the apparatus 50. Once the lumber board isreoriented onto the desired side, the lumber board traverses down theslide portion 540 of the material outfeed assembly 500. The lumber boardthen is received by the outgoing material conveyor assembly 600 whereone or more of the operators remove the processed marked and cut lumberboard from the apparatus 50.

Referring now to FIGS. 14A to 14E, the progression of a lumber board(not labeled) having a different second size and orientation (e.g.,2×12) along the material outfeed assembly 500 is shown. The lumber boardis pushed or otherwise fed along the outfeed conveyor 510 by an outfeedconveyor dog 512. The lumber board traverses along the outfeed orienter530 such that the lumber board rotates about a top portion (not labeled)of the outfeed conveyor dog 512 before the lumber board is released tothe outgoing material conveyor assembly 600. More specifically, theoutfeed orienter 530 is shaped to define or otherwise include an inclineportion 532 facing the cutting assembly 400 that enables the outfeedorienter 530 to tip or rotate the lumber board. Accordingly, as thelumber board traverses along the outfeed orienter 530, the inclineportion 532 is configured to cause rotation of the lumber board at anangle 516 that is past a center of gravity 517 for the lumber board.Thus, the lumber board tips over in a controlled and desired manner asthe lumber board is fed out of the apparatus 50. Once the lumber boardis reoriented onto the desired side, the lumber board traverses down theslide portion 540 of the material outfeed assembly 500. The lumber boardis then received by the outgoing material conveyor assembly 600 whereone of the operators removes the processed marked and cut lumber boardfrom the apparatus 50.

In various embodiments, the material outfeed assembly 500 is configuredsuch that the lumber board is reoriented as the lumber board is fed outof the apparatus 50. For example, the material outfeed assembly 500 mayre-orient the lumber board such that a printed lumber board surface isreleased from the apparatus face up. Thus, as the lumber board is fedout of the apparatus 50 the operators can clearly view the printing ormarking without having to manually re-orient the lumber board. This mayreduce the amount of lumber handling by the operators. As a result, thematerial outfeed assembly 500 may provide improved throughput of theapparatus 50 and improved safety for the operators.

In various embodiments, the material outfeed assembly 500 includes aflap (not shown) or other such member (not shown) that aids the outfeedorienter 530 to flip and/or rotate the lumber board onto the desiredside. For example, the flap may be axially aligned with and positionedaxially above the outfeed orienter 530 such that the flap contacts alumber board surface or edge as the lumber board traverses up theincline portion 532. Thus, the flap may help to tip the lumber boardover in the controlled and desired manner.

In various embodiments, the apparatus 50 may have two or more outfeedassemblies 500 spaced apart from one another like the infeed conveyors310 a and 310 b and dogged chain conveyors 330 a and 330 b of FIGS. 8 to12D. Accordingly, the apparatus 50 may include a plurality of outfeedorientation members 520. For example, the apparatus includes one outfeedorientation member 520 suitably attached on either side of each outfeedconveyor 510 of the two outfeed assemblies 500. Thus, the outfeedassemblies 500 may include at least four outfeed orientation members 520configured to reorient the lumber board as the lumber board is fed outof the apparatus 50.

The outgoing material conveyor assembly 600 is configured to receive theprocessed lumber board in the desired orientation as the lumber board isfed or otherwise output from the apparatus 50. More specifically, theoutgoing material conveyor assembly 600 includes: (1) a support frame610; and (2) a plurality of material receiving members 620 supported byand suitably connected to the support frame 610. The outgoing materialconveyor assembly 100 thus provides a suitable support structure forreceiving and conveying material such as the lumber processed by theapparatus 50.

In various embodiments of the present disclosure, the infeed assembly300, the cutting assembly 400, and the outfeed assembly 500 areadjacently positioned with respect to one another and individuallyfastened via suitable fasteners (such as bolts) to the work area floor.

In various embodiments of the present disclosure, the printer assembly200 is supported by and suitably connected to the cutting support frame410 of the cutting assembly 400.

In various embodiments of the present disclosure, the printer assembly200 is adjacently positioned and/or connected to the material infeedassembly 300.

In various embodiments, the apparatus 50 includes two material infeedassemblies 300 that are spaced apart from one another. Each materialinfeed assembly 300 includes a dogged chain conveyor 330 that conveyslumber boards through the apparatus 50. As such, the dogged chainconveyor 330 can be a continuous conveyor through the apparatus 50. Forexample, each dogged chain conveyor 330 may grab lumber boards from theinfeed conveyor 310 and convey the lumber boards through the cuttingconveyor 420. In such embodiments, the saw assembly 430 makes cuts tothe lumber boards held and conveyed by the dogged chain conveyor 330through the cutting assembly 400 and out through the material outfeedassembly 500. The dogged chain conveyor 330 then releases the processedlumber boards that are received by the outgoing material conveyorassembly 600.

In various embodiments, each of the dogged chain conveyors 330 may besplit up into two or more non-continuous conveyors that hold and conveylumber boards through the apparatus 50.
